...patient's body through the narrow gaps between the ribs, cutting holes no bigger than a nickel--a far cry from the usual 6-in. to 8-in. incisions sawed straight through the breastbone. Besides eliminating a can't-miss scar, the robotic approach promises to reduce the trauma to the body, speed recovery and minimize the risk of infection...
...Barbara, Calif., is being tested for fetal-heart surgery. Douglas Boyd, who heads the National Center for Advanced Surgery and Robotics in London, Ont., believes that robots' minimally invasive techniques could vastly improve fetal surgery's current 90% failure rate, which he says is primarily a result of the trauma placed on the womb by traditional surgical techniques. "Robots aren't just million-dollar sewing machines," says Boyd. "They are bringing a real revolution in heart surgery...
...Study came in 1997, by which time Snowdon had accumulated some 100 brains for analysis. He and neurologist Dr. William Markesbery, director of the Alzheimer's Disease Research Center at the University of Kentucky, were intrigued by an idea advanced by other researchers that strokes and other brain trauma might contribute to the dementia of Alzheimer's disease. Selecting only the brains of sisters who had earned a bachelor's degree--to eliminate any differences attributable to education--they found that among nuns with physical evidence of Alzheimer's in the brain, those who had evidence of strokes as well...
...also one of the first to suggest a way to stave off Alzheimer's symptoms. "If your brain is already progressing toward Alzheimer's," says Snowdon, "strokes or head trauma [which can produce similar kinds of brain damage] can put you over the edge." His advice: wear a helmet while biking, motorcycling or playing contact sports; buckle your seat belt; and drive a car with air bags. Meanwhile, keep strokes at bay by keeping your cardiovascular system in shape: avoid tobacco, get regular exercise and eat a balanced, healthy diet...
Protect your head from injury. Trauma to the head and even a brief loss of consciousness can eat away at precious brain reserve. The association of strokes and Alzheimer's is even stronger. So wear a helmet when biking, buckle your seat belt in the car and reduce your risk of stroke by quitting smoking, exercising regularly and keeping your blood pressure down...
